Should I use a Internal regulator or not?

I have a 65 Chevelle and I am having a guy rebuild a 327 that was not with the car. I am putting in the 327 with no existing parts and I am starting from scratch. Should I buy a internal regulated alternator or use the existing regulator? I bought a Engine harness from American Autowire but nothing is labeled and the Black/white and dark blue wires from the voltage regulator are not in this harness, but I found them on the old harness still in the car tied up and taped. The old regulator is in the car. Any input is appreciated.
Thanks

Re: Should I use a Internal regulator or not?

If you have to buy an alternator regardless, I'd go with a 1 wire, internally regulated.

We just went through this with my son's 65, but he already had a good alternator for external regulator, but no reg so we got one for him from RockAuto for about $10.

Either will work, but if you have nothing, the 1 wire is easier to set up.

If you decide on using an EXTERNAL regulated alternator...install a WELLS VR715 regulator.
A solid state regulator...much more stable and reliable...and if you're looking to keep a stock look, will even accept an original points type reg cover.
The VR715 costs about $18. AutoZone and others stock it.

If you plan to install a lot of electrical equipment that requires big power, then upgrade to a higher output internally regulated alternator. If not, then use the externally regulated one with the abovementioned solid state regulator. That is what my car has and it works well.

There reason the regulator wires were not in your new harness is that they are part of the front lamp harness, not the engine harness which you have mentioned purchasing. We can set up the front light harness either way, stock or internal. If we can be of help, let us know sir.

Curt,

Sounds like you just have to decide based on your wants and the needs of the vehicle's set-up.
